A nurse in an acute care setting is preparing to administer medications to a client. Which of the following information should the nurse obtain to identify the client?

A. Room number of the client: The room number alone is not sufficient for accurate client identification. Room numbers may change, and multiple clients may share the same room. Relying on the room number alone can lead to errors. B. Client's telephone number: The client's telephone number is not typically used as a primary identifier for medication administration. It may be part of the client's record, but it is not the primary means of confirming identity before administering medications. C. Client's full medical diagnosis: While the client's medical diagnosis is important for understanding their overall health condition, it is not a primary identifier for medication administration. Diagnoses can be complex and may not be unique to a single individual within a healthcare setting. D. Name of the client: Matching the client's name with their identification band or other official records is a crucial step in preventing medication errors and ensuring the right medication is given to the right person.
